What is basalt cardboard and where it is used

Though it may not be the first material that springs to mind when considering construction or renovation, basalt cardboard is a valuable asset in a variety of applications due to its unique properties. This material is an excellent choice for many projects that require dependable insulation and protection because it is made from natural basalt rock and offers impressive heat resistance and durability.

The remarkable quality of basalt cardboard is its resistance to extremely high temperatures. Because of this, it is a well-liked option in sectors like glass and metalworking that deal with extreme heat. It is also utilized as a heat barrier in stoves, kilns, and furnaces to ensure efficiency and safety.

Apart from its industrial uses, basalt cardboard is also being utilized in home renovation projects. It offers both thermal and acoustic insulation and can be used as a wall, floor, or ceiling insulation material. Homes are made even safer by its fire-resistant qualities, which are especially useful in regions where wildfires and other fire hazards are common.

Moreover, cardboard made of basalt is eco-friendly. It doesn’t release any dangerous chemicals or pollutants during production or use because it is made of natural rock. For those wishing to construct or renovate sustainably, this makes it a great option. Because of its durability, it also has a long lifespan, which minimizes waste and the need for frequent replacements.

All things considered, basalt cardboard is a multipurpose, eco-friendly material with a number of advantages for both commercial and domestic uses. It is an invaluable addition to any project needing dependable insulation and protection because of its exceptional blend of heat resistance, durability, and environmental friendliness.

What is basalt cardboard

From the outside, basalt cardboard looks like small, fibrous mats in a range of sizes. This term refers to a thermo-insulating material made of bentonite clay-connected, minuscule basalt fibers (1.7–1.7 microns).

The latter is a naturally occurring clay mineral that, when hydrated, swells dramatically and forms a thick gel that keeps moisture from penetrating. The process of extrusion is used to create basalt cardboard sheets by compacting, forming, and securing the individual basalt fibers with clay.

Phenol-formaldehyde resins are safe and environmentally benign because they are not utilized in the making of cardboard, in contrast to regular mineral wool. The final product is refractory and has a high heat resistance. Because of this feature, you can effectively use it to provide fire protection in areas where it’s needed, such as fireplaces, furnaces, bathrooms, saunas, etc.

Properties and characteristics

It is possible to obtain basalt cardboard in compliance with TU 95.2691-98. The sheets have a nominal size of 60 by 120 cm and a thickness of 5, 10, 12, and 20 mm (other sizes can be ordered).

The material is unique in the following technical and functional aspects:

• the possibility of heating and freezing during 2000 cycles without loss of properties;
• use at temperatures within -200 …+700 degrees;
• density-60-170 kg/m³;
• Specific weight – up to 600 kg/m³;
• humidity-not more than 1-2%;
• Sound absorption coefficient – 0.1 for low frequencies, 0.45 – for high frequencies;
• high vapor permeability, “breathing” ability;
• resistance to mold, fungus;
• service life – from 50 years;
• simplicity of cutting and installation;
• plasticity, flexibility, resistance to mechanical damage and moisture;
• Application for external and internal work.

The mice won’t settle in the basalt cardboard because it doesn’t draw in any rodents or insects. Although it can lose its primary properties at super +780 degrees and begin to compose at +1100 degrees, it is not fuel.

It is acceptable to compress cardboard sheets made of basalt by 20%; the material’s technical properties remain unaffected. Since cardboard sheets fit tightly around intricate bends, you can mount them even in curved planes.

Crucial! You can boost energy exchange efficiency and reduce heating costs by using basalt cardboard as a heat insulator.

The comfort of living in homes and apartments is positively impacted by cardboard’s high soundproofing qualities. The material can be used even in environments with high humidity because it is not afraid of moisture or fungi. The installation of the sheets won’t take long and won’t cost a lot of money because of their large size and light cutting.

Types of cardboard

Although there are several types of basalt cardboard, they are all made from bentonite clay and basalt.

Ordinary

Is a thin mat known as a BTM that has a fibrous structure. It is convenient to fix and simple to cut.

For internal operation, the material is ideal because of its small thickness (5–10 mm). The typical basalt cardboard has two drawbacks: it can shrink after prolonged use, and it gets deformed when moistened, though it can regain its original appearance.

Foil

Metal foil is placed on one side of the foil basalt cardboard, reflecting heat and minimizing heat loss in the space. The foil is secured using wire connections or glue.

The initial foil cardboard version cannot be deemed ecologically friendly due to the presence of resins in glue. Such material is not suitable for use indoors in extremely hot conditions.

Needle -punched

BIM, or needle-punched cardboard, is regarded as the greenest and safest material. Its unique basalt needles, rather than clay or glue, are used to secure the basalt fibers. The material is typically produced in rolls and has an external resemblance to felt. The drawback is that working with prickly canvas can be inconvenient, necessitating close attention to safety precautions.

Mineral wool cardboard difference

The sort of binder is the primary distinction between two widely used heaters. Mineral wool contains resins made of phenol-formaldehyde, which is actively released when heated over an extended period of time.

Mineral wool can be used as insulation for a structure if it is not subjected to extreme heat. In other situations, cardboard made of basalt is a better fit because it doesn’t include any hazardous binders.

Crucial! Density is the difference between the two materials. The indicator ranges from 13.5 to 100 kg/m³ for cotton wool and up to 170 kg/m³ for cardboard.

Made from the fibers of basalt rock, basalt cardboard is a fire-resistant, environmentally friendly material with superior insulating qualities. Because of its strength and resistance to high temperatures, it is frequently utilized in industrial and construction settings. This adaptable material is perfect for safeguarding machinery and equipment in hot environments, as well as for thermal and acoustic insulation in walls, floors, and ceilings. Because of its performance, sustainability, and safety features, basalt cardboard is quickly gaining traction in a variety of applications where dependable insulation is essential.

Areas of application of material

Because of its exceptional fireproof, heat-insulating, and soundproof qualities, basalt cardboard is in high demand across a wide range of industries and daily applications.

Insulation

In residential buildings and structures, the material offers excellent insulation for the walls, floors, loggias and balconies, outbuildings, and terraces. It is appropriate for thermal insulation of water pipes and ducts because of its thinness.

The room’s air is uniformly warmed by cardboard’s absorbing and reflecting qualities. It is possible to lay a warm floor using cardboard sheets. Additionally, it is practical to arrange them in sandwich panels and combine them with timber and log structures.

Soundproofing

The material’s ability to absorb noise is good. It works well for the layout of apartments and residential buildings to reduce noise both inside and outside.

Chimmers

Chimney insulation is frequently made with basalt cardboard. It is thin and places no load on the structure, but it forms a heat-resistant layer that offers fire protection.

Bans

When building baths, it is advised to place cardboard sheets close to the furnace. Additionally, they assist in isolating the spaces between the roof and the pipe, doors, shutters, and the bathroom.

Household equipment

Boiler heating elements are thermally insulated using basalt cardboard. It offers trustworthy sound absorption.
